I was in elementary school when it happened and tbh only a few days later the joge of Bush and Osama playing Chess and Osama having two rooks (literal German translation is: towers) already, was going viral.
I think all the "I didn't gave a fuck" ernsts in here misunderstand that is is not so much acknowledged as a personal and touching memory but the style, scope, aesthetics and political and societal consequences it brought are fascinating and keeping people attached to it, that is what is important about this event and why I give a fuck. I guess the majority of th world did not felt attacked or patriotic about it, why should it? When I was that young I couldn't care much, I was not able to comprehend what it meant that Bush was going to start a war in Afghanistan, yeah terrorist where the bad guys even back then, that is what I remember. Yet it is quite ingrained in the collective memory and when you look at the pictures it is one kind of a terrorist attack tbh, what is a wimpy vehicle going down a shopping street against that? I nearly forgot that a German Christmas market was trucked, even the Paris attacks are nothing against that. Surely, Eupore had a handful attacks since 2004, think Madrid, London and then a few years ago the internet radicalized lone wolfes of ISIS.
But tearing down to towers by plane and killing thousands, we haven't seen that before and haven't seen that again
the music is the intro to Disneys TaleSpin which is about planes and such. There was a German version making its shares during my teens.
